SLIDE FASTENER Filed Dec. 4, 1936 54 INVENTOR. JOSEPHZM SHELBERGER BY p M M ATTORNEY.

This invention relates to improvements in slide fasteners and relates more particularly to an improved slide fastener of the type wherein the individual fasteners are provided with longitudina] apertures and slots between the apertures and the side walls, the apertures being adapted to receive a beading on the marginal edges of the flexible tape or stringer. The individual fastener elements are secured in spaced relation to a flexible tape so that when the leading fastener is drawn, the others follow in said spaced relation.

Previous slide fasteners of this general character have been unsatisfactory for the reason that no suitable means had been found for securing the drawing tape to the fastener elements. A fastener made in accordance with the present invention may be constructed of any suitable material, although it is desirable to form the main body of the fasteners from plastic material. In

order to make a fastener of this type attractive in appearance it is expedient to construct the individual fastener elements as small as possible and inasmuch as articles made from plastic material frequently break or crack, each of the fastener elements in the preferred embodiment of the invention is provided with a flanged metal reinforcing plate which is secured to the rear of the fastener, the plate also serving to secure the flexible draw tape thereto.

In the drawing: V

Fig. 1 is a plan view of the improved fastener in its presently preferred form;

Fig. 2 is a broken section taken on line 22 0 Fig. 1;

Fig. 3 is a side elevation of one of the fasteners; 1

Fig. 4 is a perspective view of a slightly modifled fastener;

Fig. 5 is a central, vertical, longitudinal section taken through the fastener shown in Fig. 4.

The present invention is adapted to be used in connection with a pair of flexible tapes H] and it having cording or beading l2 along one marginal edge thereof. The tapes may be of any suitable width and are adapted to be secured directly to the edges of the opening in the garment to which the device is applied. The individual fastener elements indicated as l3 are substantially rectangular in shape and are preferably made from plastic 'or other molded material.

Each fastener is provided with a longitudinal 55 thereof. Each side Wall is formed with a. slot l8 which enables the aperture [5 to communicate with the side wall. The beading on the tapes is adapted to be received in the aperture and withdrawal therefrom is prevented by the fact that the beading is of slightly greater thickness than 5 the width of the slots l8.

The individual fasteners are mounted on a tape 20, which is desirably of substantially the same width as that of the fasteners, the fasteners being secured to the tape in spaced relation in the 10 following manner: One or more apertures 24 are drilled into each fastener from the rear side thereof and a screw 25 having self-cutting threads 26 is driven into the aperture after the tape is in place. The screw 25 is provided with a relatively 15 large head 2i, which engages a considerable portion of the tape, thereby firmly securing the tape to the fastener. By providing this large head on the screw, the individual fastener element is considerably strengthened, which makes for a. far more durable structure.

Any suitable handle device may be secured to the leading fastener, although this is not particularly essential and none is illustrated in the drawing. It will be appreciated, of course, that 25 the opposite end of the tape is suitably secured to the fabric at the end of the opening which is to be opened and closed.

In Figs. 4 and 5, the fastener is illustrated as being formed in two portions 29 and 30, with the 30 longitudinal apertures 3| and the slots 32 molded therebetween. By making the fasteners in two portions the slots may be formed with greater facility than if the fastener were made in one piece. The tape 33 is illustrated as being secured '35 to the portion 30 by means of a plurality of screws 36 positioned in apertures 35 which extend into the upper portion 29. Whereas the individual portions are initially secured together by means of a suitable adhesive, the screw 3t pass- 40 ing into the aperture in the upper portion 29 considerably aids in preventing the two portions from breaking apart. In this instance also, the head 36 on the screw 34 is suiiiciently large to 45 cover quite a. considerable portion of the tape 33.

What I claim is:

1. In a slide fastener having a pair of substantially flexible tapes or the like adapted to be united and separated, and a. bead extending along one of the marginal edges of each tape, a plurality of fasteners slidably carried by said tapes, each of the fasteners having a longitudinal aperture adjacent to each side wall thereof and adapted to receive the bead along the edge of the tape, each side wall also having a longitudinal slot of lesser width than the diameter of the aperture extending between said aperture and the side wall, each of the fasteners having an aperture extending inwardly from the rear surface thereof, a tape adapted to draw the fasteners along the beaded tapes to open or closed position, means for securing the fasteners to the tape in spaced relation, said means comprising a pin positioned in said second-mentioned aperture in each fastener, the pin having a head adapted to engage the tape, the head being of suficient diameter to engage a considerable portion of the tape and] securely join same to the fastener.

2. In a slide fastener having a pair of substantially flexible members adapted to be united and separated, and a bead extending along one of the marginal edges of each member, a plurality of fasteners slidably carried by said members, each of the fasteners having a longitudinal recess adjacent to each side wall thereof and adapted to receive the bead along the edge of the member, a tape adapted to draw the fasteners along the members to open or closed position, and means for securing the fasteners to the tape in spaced relation, said means comprising a pin positioned on the rear surface of each fastener, the pin having a head adapted to engage the tape, the head being of suflicient size to i 1;: y secure the tape to the fastener.

3. In a slide fastener having a pair of substantially flexible tapes or the like adapted to be united and separated, and a bead extending along one of the marginal edges of each tape, a plurality of fasteners slidably carried by said tapes,

anemia each of the fasteners being longitully split and having formed a longitul recess between each split portion adjacent to each side wall of the fastener, the recess being adapted to receive the bead along the edge of the tape, the split portions of each fastener having aligned apertures therein, a tape adapted to draw the members along the tapes to open or closed position, means for securing the fasteners to the tape in spaced relation and for securing the portion of each fastener together, said means comprising a pin positioned in the aligned aperture in each fastener.

i. In a slide fastener having a pair of substantially flexible tapes or the like adapted to be united and separated, and a bead extending along one of the marginal edges of each tape, a plural-,

means for securing the fasteners w the tape in spaced relation and for securing the portions of each fastener together, said means comprising a pin positionedin the aligned aperture in each fastener, the pin having a head adapted to engage the tape, the head being of sufficient diameter to engage a considerable portion of the tape and securely join same to the fastener.
